How do I fix Firefox not responding errors in Windows 10?
1. Try an alternative browser
When Firefox is not responding your only option is to try another browser, at least to fix the problem. And perhaps, you’ll decide to stick to it.
Our recommendation is to settle for another browser that comes with less to zero loading or updating issues. In this particular situation, we suggest using Opera.
Downloading Opera takes only a couple of minutes, and settings it up is extremely easy.
As you get familiarized with the design, you’ll be amazed by the multitude of features that come with this browser and how simple it is to navigate between various tabs, workspaces, and built-in social media chat apps.
The tool comes with customized versions for PC, mobile (including older phones), Mac, or Linux. Besides, you can synchronize the Opera browser across all your devices, to easily manage all the settings.
Starting from the basic version, you can bring your own flavor to the browser, adding icons, sidebars, workspaces, and bookmarks for ease of access and a better-organized workflow.
Add the incorporated VPN that secures your online activity, and you have the perfect browser.
Try Opera today and enjoy all the amazing built-in features this browser has to offer.
If Firefox is not responding it means that something stopped its processes. And a restart might be the perfect solution for reinitiating everything.
So, close Firefox (if the classic way isn’t working, close the program through Task Manager) and also restart your Windows 10 system.
Finally, run Firefox and verify if everything works as it should now; if not, go to the next troubleshooting solution.
3. Update the graphics card drivers
- Click on the Search icon.
- Type Device Manager and click on the same entry that will be displayed.
- From Device Manager expand the Display adapters option.
- Right-click on each entry and choose update driver software.
- Restart Firefox and see if you can use it now.
4. Automatically update your drivers
Updating drivers is a necessary action, but an annoying and tedious process. We recommend TweakBit Driver updater tool (approved by Microsoft and Norton) that can do it automatically for you with just a few clicks.
This tool will help you to avoid permanent damage to your PC by downloading and installing the wrong driver versions. Here is a quick guide on how to do it.
- Download and install TweakBit Driver Updater
- Allow the program to scan your PC for outdated drivers.
- Review the list of the encountered problems and see if you want to update each driver individually or all at once.
- To update one driver at a time, click the Update driver link next to the driver’s name.
- Alternatively, click the Update all button at the bottom to automatically install all recommended updates.
Disclaimer: Some features of this tool are not free.
5. Disable hardware acceleration from Firefox
- From the top-right corner of Firefox click on the Menu icon.
- From the displayed list choose Options.
- Go to the General panel and look for the Performance entry.
- From there uncheck the use recommended performance settings checkbox and also the use hardware acceleration when available feature.
- Close Firefox and initiate your web browser again.
Hardware acceleration is a feature also related to your graphics card. In some situations, depending on certain graphic card setups, Firefox might get into a freeze loop when hardware acceleration is in use, this is why we’re recommending this workaround.
6. Reinitiate Firefox files
- First, go to the Firefox official web page and download a new installer file for your Windows 10 system.
- Don’t uninstall Firefox and don’t delete anything else.
- Close Firefox.
- Go to the folder where Firefox is installed; there, rename the program folder: for example from C:\Program Files (x86)\Mozilla Firefox to C:\Program Files (x86)\Fx3805.
- Now, run the installer process by clicking on the downloaded Firefox executable file.
- In the end, open Firefox and see if this helped you.
8. Create a fresh places database
- Click on the Firefox Menu icon and select Help (question mark button).
- Go to Troubleshooting information and from Application Basics click on Open Folder.

- Firefox will be turned off now.
- Now, go to the Firefox folder and, under the profile folder, find and rename the following files: places.sqlite -> places.sqlite.old and places.sqlite-journal -> places.sqlite-journal.old.
- Restart Firefox.
New places database might fix the Firefox not responding malfunction – interrupted download processes from Firefox can cause corrupted places within the app database.
